PLAIN oILER.

,Application le. May 59,

A fundamental purpose of this invention is to provide an Voiling means 'which will be characterized (1') by extreme simplicity of construction; (2) by remarkable economy in the use of 'oil while assuring an adequate supply of oil to the part to be lubricated at all times; and (3) Vby an entire absence of valvular orother elements .calling for thought or attentionY in 'Order that the .flow of oil to the part tobev lubricated may be regulated. A particular purpose of the invention 'is to provide an eilingmeans having the lforegoing characteristics and which additionally mayfbe used wherever the 'use 0f 1111 Oil 'CHP having Material neck ,Should be employed; another particular purpose `0f theinventon .is to provide a ,most effective and economical -mfeans for perfectly .lubricating a Spring .shackle ,0r-the like which will call'for no attention, except the filling of the oil reservoir atinfrequen't intervals. i

These several purposes are ,realized from the construction illustrated in the accompanying drawings, in which :-7

Fig. 1 is a sectional view o f a spring shackle bolt of an automobile having. my

oiler applied thereto; and

Fig. 2 is a similar` View 0f a fragment of the same parts but with a slight change in .the location of the Voil feeding and il tering element.

Since all of the parts are the same in both embodiments of the iny'fention, differing only in the location of the oil feeding. and filtering elements, the same characters of reference are employed to denote correspending parts in both figures, except that the oil feeding and filtering plug is marked 26 in Fig. 1 and 26' in Fig. 2.

lO designates the rolled end of the long leaf of an automobile spring, 11 the bushing, 12 the shackle bolt and 13 the shackle links connecting the spring with the frame. The bolt 12 and a nut 14 on the end thereof, secure the spring and the 'shackle links together. Within the bolt 12 is an oil duct 15 having branch ducts 16 leading to the bushing. The head 17 of the bolt is hollow and is provided with an interiorly threaded portion 18 to receive the threaded end 19 of the oil feeder cup 20.

This oil feeder cup is a type of cup readily procurable anywhere in the open market.

" It is one form of-the well known plain 11924..l serial No.V '111,934.

oiler, so called, being that form thereof having laterally extending neck 21 externally screw th'readedat its outer vend to attach it in operative relationship with the part to belubricated. It is of inexpensive constructionandits use, therefore, as an element of lthe present lubricating means contributes to one ofthe important purposes of this invention, namely, economy of manufacture. The only other V element embodied in the invention is a wooden plug (marked 26,7in Fig. lfand 2 6 in Fig. 2) suitably arranged w i thin the oil cup 2O and serving to assure a slow and constant supply of oil to the part tobe lubricated( and to filter the oil in its passage tosaid part and thereby assure that it will be .received by the part to vbe Vlubricated in a condition free f roinsand, grit, etc. This'p'lug 'is .formed of a close grained wood, white pine preferred; with the grain running lengthwise of the plug. It is preferably subjected to a preliminary treatment to open itsy pores by removing resinous and other substances therefrom which would interfere with a constant flow of loil therethrough. A suitable treatment consists in subjecting it to a 'bath of oil heated to a temperature which will remove resinous and other liquid substances without charring or scorching the wood. lt is then preferably but not necessarily filled with a rsuitable oil,r as the lubricating oil in connection with the feeding 'of which it is to be used, the principal purpose ofthis being to cause it to more readily attract and feed the oil to the bearing vwhen in use.

yThis'plug 'is'mounted in a suitable part of the oil `cup inoperative relation with the reservoir 23 and outlet opening of the cup, to control the supply of oil through said outlet to the part to be lubricated. rlhe preferred arrangement is, as shown in Fig. 1, in the reduced opening 25 between the reservoir 23 and the chamber 22, i. e., at the entrance to the neck portion of the cup. Although it may be arranged in the neck 21 itself, preferably near the outlet end or port of the latter, as shown in Fig. 2. In any case, its fit in the opening which received it is a close one, and is preferably so close that the wood of the plug is under a substantial degree of compression. It will be noted that it may be driven to its place, or otherwise forced to its seat in the opening Q ,j y p 1,598,939

25, when the cap 2li ot' the cup is raised, the raisingof said' cap f giving free acsress to said opening. lt is obviousthat it may be inserted in the neck 2l without uncover ing any part of' the structure, when the cup is removed from the part it is to lubricate. Q' f The simplicity of this oiler is obvious. It consists only of the ordinary so-called plain oiler of the type Ihaving a neck at an angle to its body, with the dropper, sometimes forming a parteil said oiler, removed and a plug of a particular and inexpensive character inserted.

Its eiciency in use is remarkable, the structure assuring a slow but sure feed of oil in such quantity as to perfectly lubrieate the part needing oil, delivering to said part neither too much nor too little oil, the plug act-ing automatically to regulate the flow of oil from the cup to the part to be lubricated and as a iilter for theoil. The necessity of the use of any extraneous valvular or other part'to control the flow of oil and of any additional means to lfilter the oil is thereby eliminated. .y y The plug is always in its place and always operative to control the flow of oil from the cup and as thei'eis no part to be adjusted,

i and no occasion for the adjustment of anyl part, to' control the iiowr of oil, at any time,

it follows that timeand ,thought of the at! tendant is saved and danger oit oil wastage due to lack of proper attention is avoided, this resulting not only7 in a saving of the attendants time and thought and of oil but also in the avoidance of the gumniing up of the part to be lubricated which follows an oversupply oi oil thereto. i

The savings in the use of oil is remarkable, one filling lasting a. long time.

y In short, the structure has many advantages oi most practicable nature and especially ior the use ot autoinobilists as, it will assure the perfect lubrication of the part to which is applied withoutany attention whatever, other than relilling of the oil cup at reiv infrequent intervals.
